text: Inversions are thought to play a key role in adaptation and speciation, suppressing
recombination between diverging populations. Genes influencing adaptive traits
cluster in inversions, and changes in inversion frequencies are associated with
environmental differences. However, in many organisms, it is unclear if inversions
are geographically and taxonomically widespread. The intertidal snail, Littorina
saxatilis, is one such example. Strong associations between putative polymorphic
inversions and phenotypic differences have been demonstrated between two ecotypes
of L. saxatilis in Sweden and inferred elsewhere, but no direct evidence for inversion
polymorphism currently exists across the species range. Using whole genome data
from 107 snails, most inversion polymorphisms were found to be widespread across
the species range. The frequencies of some inversion arrangements were significantly
different among ecotypes, suggesting a parallel adaptive role. Many inversions
were also polymorphic in the sister species, L. arcana, hinting at an ancient
origin.

text: Understanding the phenotypic and genetic architecture of reproductive isolation
is a long‐standing goal of speciation research. In several systems, large‐effect
loci contributing to barrier phenotypes have been characterized, but such causal
connections are rarely known for more complex genetic architectures. In this study,
we combine “top‐down” and “bottom‐up” approaches with demographic modelling toward
an integrated understanding of speciation across a monkeyflower hybrid zone. Previous
work suggests that pollinator visitation acts as a primary barrier to gene flow
between two divergent red‐ and yellow‐flowered ecotypes ofMimulus
aurantiacus. Several candidate isolating traits and anonymous single
nucleotide polymorphism loci under divergent selection have been identified, but
their genomic positions remain unknown. Here, we report findings from demographic
analyses that indicate this hybrid zone formed by secondary contact, but that
subsequent gene flow was restricted by widespread barrier loci across the genome.
Using a novel, geographic cline‐based genome scan, we demonstrate that candidate
barrier loci are broadly distributed across the genome, rather than mapping to
one or a few “islands of speciation.” Quantitative trait locus (QTL) mapping reveals
that most floral traits are highly polygenic, with little evidence that QTL colocalize,
indicating that most traits are genetically independent. Finally, we find little
evidence that QTL and candidate barrier loci overlap, suggesting that some loci
contribute to other forms of reproductive isolation. Our findings highlight the
challenges of understanding the genetic architecture of reproductive isolation
and reveal that barriers to gene flow other than pollinator isolation may play
an important role in this system.

text: The term “haplotype block” is commonly used in the developing field of haplotype-based
inference methods. We argue that the term should be defined based on the structure
of the Ancestral Recombination Graph (ARG), which contains complete information
on the ancestry of a sample. We use simulated examples to demonstrate key features
of the relationship between haplotype blocks and ancestral structure, emphasizing
the stochasticity of the processes that generate them. Even the simplest cases
of neutrality or of a “hard” selective sweep produce a rich structure, often missed
by commonly used statistics. We highlight a number of novel methods for inferring
haplotype structure, based on the full ARG, or on a sequence of trees, and illustrate
how they can be used to define haplotype blocks using an empirical data set. While
the advent of new, computationally efficient methods makes it possible to apply
these concepts broadly, they (and additional new methods) could benefit from adding
features to explore haplotype blocks, as we define them. Understanding and applying
the concept of the haplotype block will be essential to fully exploit long and
linked-read sequencing technologies.

text: Combining hybrid zone analysis with genomic data is a promising approach to
understanding the genomic basis of adaptive divergence. It allows for the identification
of genomic regions underlying barriers to gene flow. It also provides insights
into spatial patterns of allele frequency change, informing about the interplay
between environmental factors, dispersal and selection. However, when only a single
hybrid zone is analysed, it is difficult to separate patterns generated by selection
from those resulting from chance. Therefore, it is beneficial to look for repeatable
patterns across replicate hybrid zones in the same system. We applied this approach
to the marine snail Littorina saxatilis, which contains two ecotypes, adapted
to wave-exposed rocks vs. high-predation boulder fields. The existence of numerous
hybrid zones between ecotypes offered the opportunity to test for the repeatability
of genomic architectures and spatial patterns of divergence. We sampled and phenotyped
snails from seven replicate hybrid zones on the Swedish west coast and genotyped
them for thousands of single nucleotide polymorphisms. Shell shape and size showed
parallel clines across all zones. Many genomic regions showing steep clines and/or
high differentiation were shared among hybrid zones, consistent with a common
evolutionary history and extensive gene flow between zones, and supporting the
importance of these regions for divergence. In particular, we found that several
large putative inversions contribute to divergence in all locations. Additionally,
we found evidence for consistent displacement of clines from the boulder–rock
transition. Our results demonstrate patterns of spatial variation that would not
be accessible without continuous spatial sampling, a large genomic data set and
replicate hybrid zones.

text: X and Y chromosomes can diverge when rearrangements block recombination between
them. Here we present the first genomic view of a reciprocal translocation that
causes two physically unconnected pairs of chromosomes to be coinherited as sex
chromosomes. In a population of the common frog (Rana temporaria), both pairs
of X and Y chromosomes show extensive sequence differentiation, but not degeneration
of the Y chromosomes. A new method based on gene trees shows both chromosomes
are sex‐linked. Furthermore, the gene trees from the two Y chromosomes have identical
topologies, showing they have been coinherited since the reciprocal translocation
occurred. Reciprocal translocations can thus reshape sex linkage on a much greater
scale compared with inversions, the type of rearrangement that is much better
known in sex chromosome evolution, and they can greatly amplify the power of sexually
antagonistic selection to drive genomic rearrangement. Two more populations show
evidence of other rearrangements, suggesting that this species has unprecedented
structural polymorphism in its sex chromosomes.

text: Both classical and recent studies suggest that chromosomal inversion polymorphisms
are important in adaptation and speciation. However, biases in discovery and reporting
of inversions make it difficult to assess their prevalence and biological importance.
Here, we use an approach based on linkage disequilibrium among markers genotyped
for samples collected across a transect between contrasting habitats to detect
chromosomal rearrangements de novo. We report 17 polymorphic rearrangements in
a single locality for the coastal marine snail, Littorina saxatilis. Patterns
of diversity in the field and of recombination in controlled crosses provide strong
evidence that at least the majority of these rearrangements are inversions. Most
show clinal changes in frequency between habitats, suggestive of divergent selection,
but only one appears to be fixed for different arrangements in the two habitats.
Consistent with widespread evidence for balancing selection on inversion polymorphisms,
we argue that a combination of heterosis and divergent selection can explain the
observed patterns and should be considered in other systems spanning environmental
gradients.
